Question

find the mean, \\(\overline{x}\\), of the data.\
147, 141, 120, 124, 128\
\\(\overline{x} = ?\\)

Explanation:

Step1: Sum the data values

We add up all the given numbers: \(147 + 141 + 120 + 124 + 128\). Let's calculate that: \(147+141 = 288\), \(288+120 = 408\), \(408+124 = 532\), \(532+128 = 660\).

Step2: Divide by the number of data points

There are 5 data points. So we divide the sum by 5: \(\frac{660}{5}\).

Answer:

\(132\)
